Developer Grimwood Team has announced that its grim puzzle-platformer, World of One, is launching on PC, Mac, and Linux on April 27, 2017. World of One is a puzzle-platformer with 'planet-based physics where you plunge into the grim and dark atmosphere of discouragement and depression.' In the game you have to find out why you live in this world, how did you get there, and why there are so many questions, yet so few answers. Throughout the game you will be traveling between planets, trekking through ominous and sullen rain. Planets will be filled with deadly traps, puzzles, and horrible monsters that are all trying to kill you.
